...which could be just about anywhere, as the thousands of Protestant denominations, each the "one true Church of Christ, each "acting under the guidance of the Holy Spirit", attest.

It's interesting that you criticize Protestants for this. Show me anywhere in a Protestant church's statement of faith (or like document) that claims it to be the one true church. We generally believe that all true believers in Christ, regardless of denomination, make up the true church. Now I have read many RC documents that actually do make this arrogant claimof being the "one true church" and any honest Catholic will agree that the official view of your church is exactly this.
You are misinformed.
